Apple picks adaptive
frequency hopping solution

Apple has selected CSR's BlueCore chips with adaptive frequency hopping (AFH) to Bluetooth-enable its line of professional PowerBook G4 notebooks

Apple offers its PowerBook G4 customers Bluetooth wireless technology to easily enable wireless exchange of data between other Bluetooth-enabled devices including computers, cellular phones, PDAs and the new Apple wireless keyboard and Apple wireless mouse. The BlueCore chip offers AFH, a system that eliminates interference between Bluetooth and other RF devices, such as WiFi (802.11) that operate in the 2.4GHz radio frequency band, by co-ordinating the frequency channels of all 2.4GHz devices.

As the number of computers fitted with both Bluetooth and WiFi wireless connectivity increases so does the value of AFH.

Interoperability prototypes were made available first by CSR and were used by the Bluetooth lead adopters including Apple to validate the new AFH standard.

'Apple has lead a number of introductions of communications technologies to the personal computer world including Ethernet, AirPort (802.11b) and FireWire (IEEE1394)', said Glenn Collinson, Sales Director and cofounder of CSR.

'Apple's integration of Bluetooth into their computers will likewise accelerate its mass market adoption and CSR is delighted to be supplying Apple's computer division with Bluetooth ICs for its PowerBook G4 notebooks'.

'Apple was first to integrate Bluetooth into its operating system with Mac OS X and now the first to make it a standard feature across our entire line of professional notebooks', said Greg Joswiak, Apple's Vice President of Hardware Product Marketing.

'We've worked with CSR to be first to deliver adaptive frequency hopping to our PowerBook customers to provide an exceptionally reliable and interference free wireless experience'.

CSR's BlueCore silicon was the first single-chip to provide Bluetooth functions, and, alongside the development and implementation of AFH, demonstrates the progressive approach that CSR has taken with its technology.

CSR's technology and the ability to deliver in high volumes are important deciding factors when companies like Apple are looking for quality Bluetooth solutions.
